Alright I have had this tank only a few days.
But my ammonia seems rather low for one figure 8 puffer. He is a messy eater so a lot of food just falls to the bottom of the tank.
This was a used aqaurium and I did not change the bio wheel in the filter.
When I picked up the tank it looked like it hadn't been used in a while though.
Is my nitrate cycle barely starting or is it nearly finished?
I know it is mean to use live fish. However this fish was bought for me when I was sick and before I knew about the nitrate cycle. He's doing fine!!
